Cleveland C33814 Square End Mill 5/16 in 2 Flute Hss Ticn

Product Description

The CLEVELAND C33814 is a 2-flute square end mill designed for precision milling in ferrous and non-ferrous materials. Built from high speed steel with a titanium carbonitride (TiCN) finish, it delivers extended tool life in demanding cut conditions. The 5/16 inch cutting diameter pairs with a 9/16 inch length of cut and a 3/8 inch straight-cylindrical shank with Weldon flat, keeping the tool seated firmly in standard end mill holders. A 30-degree helix angle and spiral flute geometry promote efficient chip evacuation. This is a centercutting tool, meaning it can be plunged axially as well as used for peripheral and slot milling. Machinists and tool-and-die professionals specify this series for general-purpose work across steel, cast iron, and non-ferrous metal applications.

The C33814 belongs to Cleveland's HG-2 series, a regular-length line engineered for everyday shop use where rigidity and repeatable tolerances are the priority. Its right-hand cut and right-hand flute configuration suits conventional CNC machining centers, knee mills, and manual bridgeport-style setups. The 2-flute design is particularly effective in softer metals and slotting operations where chip clearance is more critical than surface finish speed. Typical end users include production machinists, maintenance mechanics, and mold-and-die shops working with a broad range of workpiece materials.

Key Features

• TiCN coating increases surface hardness and reduces friction for longer tool life versus uncoated HSS
• Centercutting geometry allows both plunge and peripheral milling operations
• 30-degree helix angle promotes smooth cutting action and chip evacuation
• Weldon flat on straight-cylindrical shank resists pullout in set-screw holders
• Right-hand cut and right-hand flute for standard spindle rotation
• 2-flute configuration maximizes chip clearance in slots and softer materials

Compatibility

Designed for use in standard 3/8 inch end mill holders, collet chucks, and Weldon-flat set-screw holders. Suitable for milling cast iron, non-ferrous metals, and steel workpieces as noted in the manufacturer specification for primary workpiece materials.

Installation Notes

Installation is performed by qualified machinists following standard tooling change procedures. Power down and lock out the spindle before securing or removing the end mill from the holder. Verify holder bore size matches the 3/8 inch shank diameter and that the set screw engages the Weldon flat squarely. Confirm spindle rotation direction matches the right-hand cut specification before starting the machine.
